Remove text between headers while leaving headers intact

Hi,
I'm trying to strip all lines between two headers in a file:

### BEGIN ###

[Header 1]
Text to remove, contains all kinds of characters

FastSpeedTest.com (USA)=http://fastspeedtest.net/mirrors/spybot/
...

[Header 2]
More stuff, more headers

### END ###

I've tried several different sed commands, and the results have been either nothing is removed, or the line [Header 2] is removed as well.

Sorry, I haven't saved a list of what I've tried; here is my most recent failed attempt though:

sed -e '/\[Header\ 1\]/,/\[Header\ 2\]/ { /^\[Header\ 2\]$/!d }

Any help would be appreciated, and thank you in advance =)

NAME
ident - identify files SYNOPSIS
ident file ... DESCRIPTION
Ident searches the named files for all occurrences of the pattern $keyword:...$, where keyword is one of Author Date Header Locker Log Revision Source State These patterns are normally inserted automatically by the RCS command co (1), but can also be inserted manually. Ident works on text files as well as object files. For example, if the C program in file f.c contains char rcsid[] = "$Header: Header information $"; and f.c is compiled into f.o, then the command ident f.c f.o will print f.c: $Header: Header information $ f.o: $Header: Header information $ IDENTIFICATION
